    Sammanfattning : One of the worst wildfires in Portugal in 2017 on June17- 21 started at the central part of Pedrógão Grande and spread fast to the surrounding areas Góis, Pampilhosa da Serra and Arganil. The wildfire took 64 lives and a large smoke plume was observed. LÄS MER

  2. 2. Super-Resolution for Fast Multi-Contrast Magnetic Resonance Imaging

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Erik Nilsson; [2019]
    Nyckelord :Deep learning; convolutional neural networks; CNN; super-resolution; MRI;

    Sammanfattning : There are many clinical situations where magnetic resonance imaging (MRI) is preferable over other imaging modalities, while the major disadvantage is the relatively long scan time. Due to limited resources, this means that not all patients can be offered an MRI scan, even though it could provide crucial information. LÄS MER

  3. 3. AN EVALUATION OF REAL-TIME GLOBAL ILLUMINATION TECHNIQUES

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Johan Sundkvist; [2019]
    Nyckelord :;

    Sammanfattning : Real-time global illumination techniques are becoming more and more realistic as the years pass and new technologies are developed. ‘This report therefore set out to evaluate di‚fferent implementations of real-time global illumination.‘ The three implementations that are looked at are Unity, Unreal and a Voxel Cone Tracer.

  4. 4. Objective Perceptual Quality Assessment of JPEG2000 Image Coding Format Over Wireless Channel

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Bala Venkata Sai Sundeep Chintala; [2019]
    Nyckelord :Discrete Wavelet Transform DWT ; Image Coding Format; JPEG2000; Objective Perceptual Quality assessment; Quality of Experience QoE ;

    Sammanfattning : A dominant source of Internet traffic, today, is constituted of compressed images. In modern multimedia communications, image compression plays an important role. Some of the image compression standards set by the Joint Photographic Expert Group (JPEG) include JPEG and JPEG2000. LÄS MER
